ROAD AY SANDER.

Application filed December 1, 1923. Serial .No. 678,055.

To all whom it may concern.

Be it known that I, OMI GRANT PHILLIPS, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain-new and useful Improvements in Roadway Sanders; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains so that sand will be automatically discharged in front of the braking wheels, as

.soon as the brakes are applied thereto, provision bein made however, whereby the discharge 0 sand may be prevented when its use is not necessary,

in most instances, the sanding device is operated only to a limited extent, by application of the brakes, and a further aim is to provide a separate control means whereby the sander may be more effectively operated if desired,

Yet another object of the invention is to provide a manual control means having two functions, one function 'beingeto hold the sander against operation with the brake mechanism if desired, while the other tune-- tion is to operate the sander more effectively than it can be operated by the rakes, the more eiiective operation being in most instances controlled, by effecting. greater openof a sand discharge valve.

et another object of the invention is to provide means for utilizing the exhaust gases from an automobile engine to heat thesaud in a sand container to keep the sand in a dry condition and prevent packing and con se uent clog ing of the outlet.

%ith the Foregoins in view, the invention resides in the novel subject matter hereinafter described and claimed, the description heing supplemented. by the accompanying drawing: 7

Figure l a section,

connected with the brakes of the vvehic e by which it is carried,

ing means bein held against operation by a manually HdJIlStfiblG control rod.

Figure 2 is a view similar to Fig. 1, but showing the control rod moved to another position, permitting limited operation of the sander under the influence of the brakev mechanism.

Figure 3 is a view similar to Figs. 1 and 2, butillustratihg the control rod moved to still another position, for the purpose of permitting greater discharge of'sand.

Figure dis an elevation partly in section, illustrating the manner in which the sand container is heated by the exhaust gases from the engine. v

In the drawing above briefly described, sanding means have been shown, supported by transverse bars 1 which are in turn secured to a vehicle frame. This sanding means, in the present disclosure, includes a sand container or hopper Q having an outlet neck 3 and a. rotary slide or control valve t for said neck. Preferably, two of the containers are provided on the same machine, with their outlets in position to discharge sand immediately in front of the rear wheels. On machines using four wheel brakes, it is obvious that provision may he jmade for discharging the sand in front of all four wheels.

The valve 4 is shown provided with a controlling member, preferably in the form of an upstanding cranlr arm 5 which may be connected by a suitable spit ing device 6 with a portion of the vehicle frame as indicated at 7, so the valve iis normally held closed, as shown in Big. 1. An operating" rod 8 has been illustrated, passing slidably through a guide 9 carried by the arm 5, said rod having an elastic connection with the arm, which connection is preferably established by means of a coiled compres" sion spring 10 hearing at one end against the arm 5 and at its other end against a nut or other shoulder 11 on said rod. The front end of the rod 8 is adapted for ooirntiection with the brake mechanism of the automobile or other vehicle upon which the sander is l k ll t t usue, ano or sa e or i. usira. io 1-. nave shown. said rod connected directly with a foot bralre pedallf), so that when certain ice tion, when its use is not desired, this means being preferably of the construction de scribed below.

A horizontel rod 13 hes been sl.-own,

pivoted to the upper end oi the mm 5 at one of its ends, as indicated at 14:, the other end of sold rod having e guide eye L5. Passing slidebly through this g iide eye, is e control rod 16 whose rear end is formed with e guide eye'l'i through which the rear portion of the rod 13 passes slide-lily. The front end of the rod 16 is adopted to he connected with any suitable hend control, such es the lever 18. When the use of the sender is not required, the rod 16 is moved. reerwerdly until its guide 17 strikes the upper end of the emn 41- end thus prevents the letter from moving forwerdly when the brakes ere applied. The application of the brakes is not interfered with however, es the elestic connection 10' will yield end permit seid brakes to o erete. When the rod 16 is moved for-were y to the position disclowd in Fig. 2, it will he seenthet operetion of the brake mechanism to apply the brakes to the machine, will swing the arm 5 forwerdly to e limited extent, thereby pertielly opening the valve 4t end allowing some discherge ot' send. lit the ernonnt of sand then discherged is insnfiicient, the rod 18 may he pulled still further forward, until its guide 17 strikes at stop 19 on the rod 13, whereupon further forwerd movement of seid rod 16, will pull the velve erm to e greeter extent, thereby permitting greeterl opening of the valve, es will he cleer by reference to is, v lln ord r that the send in the container 2 iney be kept dry, I prefer to provide the lower portion of said oonteiner with e heating chamber 20 into which enhenst gases from the engine discherged, in the present disclosure, pipe 21 is shown lead ing from-the engine mntller 522 conduct the a see to tie cheinher 20, which. they may escepe, for instance through opening 23.

lit will be seen from the foregoing thet the invention is rether simple and inexpensive, yet will he highly eilicient end desir ehle, regerdless of the "form of vehicle upon which it is used. However, attention he directed to the feet thet while the novel. opereting means for the is proton no use in connection with s: der heving hen-ting .nieens, said rneens might used in ii other rec-noes forms of senders. Similerly, the heating; feature of the sender is applicable to numen ous types of sending mechanisms, regardless of the erect manner in which they ere operated.

Excellent results ere ohteineble from the deteils disclosed and they are therefore preferably followed, but within the scope or: the invention es cleinied, niinierous changes may he made. Un touring cars, the send conteiners ere refereoly in the bechoi the front seat, hid en from view, with conven ient openings for filling.
